SHU LL REVERSIBLE SEX-MUTANTS

associated with functional stamens, were of such anomalous char- 

 acter that they have not been included among the 8 recognized 

 hermaphrodites found in normal families in 1909, but they will be 

 mentioned later under case XIII in connection with the somatic 

 hermaphrodites C and D of my preliminary report.

(Mutant) 



None of the new hermaphrodite mutants 

 discovered in 1909 were successfully self- 

 fertilized, and the pedigrees here reported 

 are repeated from my former paper for the 

 sake of completeness. All the self-fertilized 

 hermaphrodites which yielded progenies in 

 my 1910 cultures belonged to a later genera- 

 tion, being offspring of a self-fertilized her- 

 maphrodite and not the progeny of new mutants. They conse- 

 quently belong to a separate case and will be considered next. The 

 agreement of these results with those under case I leads to the con- 

 clusion that the eggs of the hermaphrodite are all of one type, 

 that is, female-bearing, like those of the females. The significance 

 of this result will be considered later.
